Keane, the Villans ' assistant manager, accused Mourinho of trying to belittle his fellow managers and coaches – and claimed that the Chelsea boss would be punched if he tried to do the same in Sunday League football.

Asked why he refused to shake Mourinho’s hand, Keane said: “Because the game is still going on.

“I don’t mind all that but the game is still going on. It’s disgraceful, I’ve seen him doing it to other managers, it’s a disgrace.

“The game is still going on. You wouldn’t do that on a Sunday morning, you would get knocked out.”
